Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.6% of the total across 187 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 19 manufacturers, the largest accounting for just 12.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $2,559 and has fallen 99.1% since, to $23 in 2022.
Across 187 payments — averaging $16.29 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
